3. Deployment of the wind • Sweden (2007) : 1 % of the country’s net electricity consumption • Corresponds to 1.4 TWh • Political decision (2002): • Production of 30 TWh prior to 2020 • Germany: 7,5 % (Source: GWEC, Global Wind Energy Council) • Spain: 11 %

4. Impact on radiosystems • Conducted studies confirms that fixed systems like Radar-, RadioRelay, Brodcasting-systems and RAS may experience disturbances due to obstruction and/or reflection caused by turbines. • In the case of Radars, shadowing and/or reflexions is the main problem when considering off-shore windturbines vs coastal surveillance radars. • The potential for these disturbances depends on the size of the turbine, material, location in relation to the ”victim” etc • For RAS, even EMC caused by the generator may cause disturbance in case the separation distance is not sufficiently large.

5. Protection • Exclusion zone around the RAS-site may provide sufficient protection if the zone is large enough. • Guidance on this zone, given by international recommendation(s), would be useful?

6. Responsibility of the Swedish agency • Provide, to the operator of wind turbines, a list of potentially concerned operators of radiosystems in a certain geographical area. • The intention with this procedur is to establish a ”marriage” between concerned operators with the objective to create a fruitful environment for coordination. • It should be noted that the agency is not responsible for the licensing of turbines. This issue is handled by the local authorities. • The agency is responsible for the protection of radio services only.

7. Web-site Vindlov (www.vindlov.se) - Swedish Energy Agency responsible for this site developed in cooperation with 20 authorities (incl the telecom agency) • - The objective is to provide information covering all aspects of the complicated process of licensing
